WIRING MECHANISM FOR. AUTOMOBILE-ENGINES.

T 0 all whom it may concern Be it known that I, IRA H. SARE, a citizenof the United States, residing at Sentinel, in the county of Washita andState of Oklahoma, have invented certain new and useful Improvements inWiring Mechanism for AutomobileEngines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to wiring mechanism for the ignition system ofautomobile engines and particularly to the wiring for the primarycircuit of a system in which a magneto and induction coils are included.

It is a well known fact that in some classes of automobile engines, thewires running from the timer to the primary coils, become saturated withoil and thus become short circuited and it is to obviate the troublethus caused that is the primary object of my invention. I obtain thisobject by providing permanent wiring connection between the timer andprimary coils, portions of the wires included in said connections beingremovable for renewal, at small expense.

Another object is to provide novel connect engine side of the dashboard,showing theconnecting means between the primary coils and the timer,Fig. 3 is a sectional view on the line 33 of Fig. 3. Fig. 4 is a view ofa portion of the connection between the timer and primary coils. showingthe timer in front elevation. and showing the metal case in sideelevation, Fig. 5 is a vertical sec tional view through the metal caseand adjacent parts, Fig. 6 is a bottom plan view of the metal case, and,Fig. 7 is a diagrammatic View of the wiring system of an engine inconnection with which my improve ment is adapted to be used.

Referring more particularly to the drawings, in Fig. 1, 1 represents thefront cylinder of a four-cylinder engine, 2 represents the radiator, 3the dashboard and f the timer, the commutator of which is keyed orotherwise secured to the cam shaft of the engine (not shown).

The primary circuit in the system indicated in Fig. 7 extends from themagneto 5 to the commutator of the timer 4, through the timer to theprimary circuit wires 7 and thence to the primary coils of the inductioncoils indicated at S. The secondary circuit extends from the secondarycoils of the induction coils, through the secondary wires 9 to one poleof the spark plugs 10. through the spark plugs, which have'the oppositepole grounded in the engine, through the engine back to the magneto 5,which also may have one pole grounded in the engine casing.

As a rule the binding posts 11. of the timer are connected by singlewire to the binding posts 12 of the primary coils and it is at the pointnear where the wires connect with the timer that oil and grease from theengine accumulates and saturates the wires and thus cause shortcircuiting.

In my improvement I connect the binding posts 12 of the primary coilseach with an insulated wire 13, and these wires extend through one ofthe walls of a tubing 14 and are threaded through that tubing andproiect somewhat beyond the outer end 15 thereof (Fig. 5). As seen inFig. 2. the inner end of the tubing rests against the front face of thedashboard 3, or that face which is nearest the engine, the binding post12 of the primanv coils extending through the dashboard. The tubingiswound around a brace rod 16. which connects the upper portion of theradiator 9 with the dashboard, the front end of said tubing dependingbelow tbe brace rod 16 and isspaced from the front of the cylinder 1 bymeans of a wire fork 17 which is secured to the cylinder 1 mv means of abolt 18. said bolt being one of those which serve to hold the enginetogether.

A substantially cup shaped casing 19, made of aluminum or other metal.has a reduced end 20, which is headed as at 21, ex tended into the frontend of the tubing and secured thereto by means of a clamp" 22. The lowerend of the casing 19 is of con siderable greater diameter than theportion 20 thereof and a disk of fiber insulation 23 and is secured tothe lower edges of the casing 19 by means of the threaded rim 24, whichis provided with a flange for securing the disk 23 to the casing, acircular washer 26 being interposed between said flange and disk. Atfour diametrically opposed points the disk 23 is perforated, as at 27,and through these perforations extend bolts 28, the heads 29 of whichbear upon the ends of the wires 13, said ends being twisted around 7 andagainst the nuts 39., or otherwise secured to the bolt 28, is the upperend of an insu- 'lated wire 34, said end being secured in place by meansof the thumb nut 35. The lower end of the wire connects to one of thebinding posts 11 of the timer, it being understood ,that each of thewires 13 is thus connected by means of one of the bolts 28 and by thewires 34 with one of the binding posts 11 of the timer. The connectionbetween the timer 4 and the secondary coils is the same as beforedescribed.

The wires 3% are held in spaced relation from the front of the engineand are kept.

in an upright position, and are spaced from each other between the timer4 and the casing 19, and are thus not liable to become oil soaked, butshould they become soaked with oil and short circuited any one of them,or all of them, may be quickly and easily re- ,moved and new ones put intheir stead at very small expense. In the ordinary system of this typethe wires from the timer 4 are bound together and run horizontally tothe frame of the automobile, along the frame under the lower edge of thehood and up to the dashboard where they are connected with the primarycoils of the induction coils and, when they are thus arranged, it hasbeen found that oil and grease from the engine becomes collected on thewires near the timer andgradually soaks through and thus causes shortcircuiting at that point. When the Wires became thus short circuited, itwas necessary to remove the entire length of wire connecting the timerwith the primary coils and this involved considerable trouble andexpense.

The tubing 14 may be made of any flexible material which is water andfire proof, and if it is so desired, it may be made of insulatingmaterial.

Uopies of this patentfmay be obtained for Although I have described thepreferred embodiment of my invention, I reserve and may exercise theright to make such changes in the construction, combination and errangement of parts as do not depart from the spirit of the invention andthe scope of the appended claims.

What I claim as new is:

1. In a wiring system for combustion engines for motor vehicles, thecombination with a plurality of engine cylinders, of a timer positionedat the front of said cylinders, a plurality of primary coils supportedat the rear of said cylinders and having connections therewith, aflexible tubing supported above said cylinders, said tubing having oneend secured in proximity to said 'coils and its 0 osite end dependin atthe a PP 1 e front of said cylinders in proximity to said timer, asupport for the depending end of said tubing, a connecting joint uponthe depending end of said tubing, a plurality of wires incased withinsaid tubing and connecting said coils with said connecting joint,

and a plurality of separated unincased wires connecting the wires ofsaid joint with. said timer.

2. In a wiring system for combustion engines for motor vehicles, thecombination with a plurality of engine cylinders, of a timer positionedat the front of said cylinders, a plurality of primary coils supportedat the rear of said cylinders and having con nections therewith, aflexible tubing sup ported above said cylinders, said tubing having oneend secured in proximity to said coils and having a plurality of spacedapertures therein, and its opposite end depending at the front of saidcylinders in proximity to said timer, a forked member upon the frontcylinder for supporting the depending In testimony whereof I have signedmy v name to this specification in the presence of two subscribingwitnesses.
